I was convinced we shouldn’t bother releasing Rattle, because even half of our fans hated it.

Paul Baumer

When the duo first tested out house music stormer Rattle in the clubs, many dancies loathed the catchy track.

Band member Paul Baumer told me: “I was convinced we shouldn’t bother releasing Rattle, because even half of our fans hated it.

“It took two months for people to be won over, maybe because it’s such a different sound for us.”

Paul and bandmate Maarten Hoogstraten, both 31, will buy “a very expensive bottle of champagne” to celebrate with their girlfriends and parents at home in Holland if Rattle knocks will.i.am, 37, off top spot tomorrow.

Paul admitted: “We play over 200 shows a year, so when I’m at home I’m usually very boring.

“I just want to sit on my couch and watch a movie. But having a No 1 in the UK is huge.

“There’s no way I’m going to try to pretend to be cool about it and say it’s no big deal.

“I thought we had a chance of making the Top 10, but No 1 is beyond our expectations.”

Maarten and Paul definitely won’t hit their local bingo hall for a party.

Paul laughed: “I’ve never played bingo. People think our grandmothers must be big bingo players or that it’s some other tribute, but there’s no deep meaning to the name at all – it’s just a friend’s MSN Messenger alias that we thought sounded cool.”

The name was Maarten’s idea, after they’d toyed with calling themselves Christian And Marchand, the pair’s middle names, or Night Moves. Paul explained: “We wanted a name that stood out, not just ‘DJs so-and-so’.

“We’ll have to play bingo one day – maybe when we come over for our UK tour in March.”
